In the north west, the judges must choose between a 17th-century coastal cottage on the Llyn Peninsula, a semi-detached family home in Colwyn Bay and an arts and crafts cottage in Conwy.

Scoring them on architectural merit, distinctive design and original style, which home will Owain, Mandy and Glen judge worthy enough to go forward to the grand final?

The first home for the judges to visit dates back to the 17th century. Glan Soch is a traditional Welsh cottage on the Llyn Peninsula, and is now home to Emma, husband, Elwyn, and Bunny the dog. After purchasing the property in 2008, the couple spent three years restoring the building while carefully retaining as many original features as possible.

Second on the hit list is Bronant, a semi-detached family home in Colwyn Bay, home to Silvana, Julian, daughter Robyn, and dogs Milo and Harvey. The family have revamped the space since moving in six years ago, knocking through walls and expanding into the garden to create a haven of relaxed living and socialising.

The third and final contender is a Grade II listed cottage in Conwy. Tyn y Coed was designed by arts and crafts architect Herbert Luck in early 20th century and is now home to Hayley, Craig and son, Hari, who have made the unique property their own, adding their interior style and enhancing the light, bright, country feel of this family home.
